THIS WAS THE INFORMATION BEFORE THE ACHIEVEMENT WAS CHANGED. THEREFORE THIS INFORMATION IS OUTDATED.

According to the dungeon journal Megaera has 4 heads. The 4 heads are (as the achievement requirements say): Fire, Frost, Poison and Arcane.This achievement requires you to kill one of Megeara's heads first, meaning you have to kill him 4 times with on each visit killing an other head first.The hard part will likely be the different heads, because when you kill a head, 2 heads will respawn, 1 on the original spot and 1 in the fog. Meaning if you kill a head, you will take two times more damage of that school. Also, Megeara gains a buff called Hydra Frenzy, which will heal all his other heads to 100% and increases the damage of the school of the killed head by 30% and applies a buff called Elemental Blood of Megaera. This effect increases the damage done by 10% per create head. These effects stack!Also what is quite unusual, the Arcane head seems to be heroic-only. This means that, to gain this achievement, you have to have killed Megeara on Heroic difficulty with the arcane head slain first. My theory will be that the Arcane head will be the hardest head, since this is added on the heroic version of the encounter. (unconfirmed of course)

So what do the heads do?The heads seem to cast different spells depending if they are in Concealing Fog or not. How this fog behaves is as of today unknown, since the boss hasn't been up on the ptr yet for testing purposes. Everytime a head is killed, a new head respawns and in addition to that a head will spawn in the fog with another ability. Keep in mind that if more than 2 heads are out of the fog, Megeara will go on Rampage after a head is killed. Also if there are heads up and there are no players within melee range, Megeara casts Megaera's Rage.All heads use front cone attacks placing certain debuffs on the players which stacks. This will likely be a tank-only mechanic and tanks will have to swap to get rid of this debuff.

The fire head also casts Cinders when in the fog. This is a debuff which, after 30 seconds or when dispelled, places a fire pool on the ground.

The frost head uses Torrent of Ice. The journal does not say this will only be cast when in the fog, but according to all the other information it will likely be. This attack will place a puddle on a random target. This puddle can be removed by a person who has the Cinders debuff and gets dispelled while in the puddle.

The poison (Venomous) head uses Acid Rain while in fog. This is a bolt cast on a random target. When this bolt reaches ground it will do raid-wide damage. This damage increases the further you are away of the impact.

The arcane head, keep in mind this is heroic-only, uses nether bomb while (likely) in fog. This is a orb that, when landing on a player, causes 360-390k damage to the player. If the orb isn't absorbed, the orb deals 95-105k damage to all players. However, the players who take damage gain the debuff Empowered. This increases your healing and damage done, but also increases your arcane damage taken. This means that if you get hit twice in a row, you take 700k damage which will mean you will die if you are not high on health.

Because not all the information is confirmed, I will try to update this post after ptr testing is done and mechanics have been datamined.Edit: updated according to first ptr testing round.

the difficulty of this achieve comes from Elemental Blood of Megaera. each time a head of a specific color is killed, it increases the damage done by other heads of that color for the rest of the fight. normally, one would kill the required 7 heads and cycle through the colors evenly. by not killing any heads of a specific color, it ensures that the stacks for the other 2 colors will increase at a faster rate, increasing the amount of healing required and the rate at which they do their special abilities (cinders, ice beams, explosions).

the currently popular strategy for heroic is to not kill green heads.

Killing Megaera without killing a Frost head isn't that bad; my guild's normal kill order only involves one frost head. The issue is doing it without killing either Venom or Flaming because that means killing a minimum of 3 Frost heads, which means lots of beams to kite.

First time here you will pick one color to leave alone out of Red, Blue or Green. Say you want to leave Red alone and you just kill Green and Blue heads. That will give you one prong of the achievement.

Next week, you kill for example Red and Blue and you leave Green alone.

The week after, say you kill Red and Green and leave Blue alone.

Just make sure your party knows what color to leave and you'll be fine that week. Three weeks running, and you'll have this under your belt!

Each week, you have to only focus on 2 of the 3 colors and making sure each of the selected color never gets targeted, you'll get this down.
